Overview
The Extech Heavy Duty Light Meter enhances accuracy by selecting one of four lighting types: tungsten/daylight, fluorescent, sodium, or mercury. The meter utilizes a precision diode and color correction filter and adjusts for cosine and color-corrected measurements. The microprocessor assures maximum accuracy through an Fc range of 200.0, 2000, and 5000Fc and a lux range of 2000, 20,000, and 50,000 lux.
Data Storage
The built-in RS232 serial interface provides a connection with the optional Windows Data Acquisition Software, which enables users to display and capture readings on a PC and set time intervals and alarms. The battery-operated datalogger module stores over 8000 readings for later transfer to a PC.

Sustainable Fishing in Alaska: Protecting the Salmon Capital of the World through Research
In the far north, the Alaska Peninsula stretches away from the Last Frontier into the Pacific Ocean. A narrow strip of land dotted with freshwater lakes and intruded upon by ocean inlets–this unique region is intimately connected with the surrounding water. Nestled halfway down the peninsula's southern coast are the small villages of Chignik. The area has historically been home to the Aleut people and has been heavily reliant on fishing for centuries. Home to commercial and subsistence fishing today, Chignik continues to rely upon the salmon returns to the surrounding villages, which are supported by scientists working tirelessly to understand and steward these fish populations.

NexSens X3 Data Logger Review
Extreme environments meet extreme design with the NexSens X3 Data Logger . The new logger offers the latest in real-time monitoring technology with wireless communication, a large plug-and-play sensor library and ultra-low power consumption, all in a waterproof marine-grade housing. The X3 is built to handle harsh weather, floods, high winds and rough seas, and it stands alone; no additional protective housing needed. With an operating temperature that ranges from -40°C to 70°C, the logger can withstand arctic environments and extreme heat. A conformal coating on the internal circuit board isolates it from moisture and humidity.

Buoy-Based Solutions: Strengthening Kentucky’s Emergency Response Efforts
When Kentucky’s Emergency Response Team (ERT) has to act quickly in response to chemical and oil spills in the Commonwealth, they rely on small, easily deployable buoys to collect critical data that help minimize and evaluate damages in environmental emergencies. With a background in geology, Robert Blair primarily worked with groundwater and got involved sporadically with the ERT during groundwater contamination emergencies. Over time, this involvement led to him joining the ERT as an On-Scene Coordinator and then becoming the branch manager for the team and overall Emergency Response Branch .
